Neanderthal DNA in Modern Humans

Non-African people carry remnants of the Neanderthal X chromosome, suggesting interbreeding with early human ancestors.

New evidence confirms suspicions that early modern humans, which left Africa some 300,000 to 750,000 years before Neanderthals, probably interbred with the physically stronger hominid species. The contact likely happened in the Middle East, the authors said, sometime after early modern humans left Africa 80,000 to 50,000 years ago.

Damian Labuda of the University of Montreal and the CHU Sainte-Justine Research Center and his colleagues analyzed a particular segment of the human X chromosome, one of the two sex chromosomes, known as dys44—an 8-kilobase intronic region that flanks the human dystrophin gene and has proved to be a useful marker for human evolutionary studies.Thanks to last year’s complete sequencing of the Neanderthal genome, the researchers could compare the genomes of more than 6,000 modern humans with the ancient hominid, and found similar intronic sequences on the Neanderthal X chromosome, as well as on the X of people from all continents except sub-Saharan Africa. The results are published in the July issue of Molecular Biology and Evolution.

“There is little doubt that this haplotype is present because of mating [of] our ancestors and Neanderthals,” Nick Patterson of the Broad Institute of MIT and Harvard University said in a press release. “This is a very nice result, and further analysis may help determine more details.”

Correction: This story has been updated from its original version to correctly indicate that modern humans left Africa after Neanderthals. The Scientist regrets the error.

With regard to Neanderthals it is nice to be vindicated at last. nearly 50 years ago I tried to postulate that there are those today who carry the Neanderthal gene, I was rubbished. My contention was that it would be unlikely that bigger stronger and larger brain capacity would give way completely to homo sapiens completely. I still contend that spaiens developed best inÂ HOSTILE conditions such as that in Africa. High breeding, with a high level of irrationality, which has distinct survival value in that situation.Neanderthal survived in HARSH conditions where logic and forward thinking were vital as was collecting and hoarding. Instead of competing for food they co-operated and had reduced levels of breeding. It explains a about human behaviour today. I am not suggesting that one is bett than another only that different environements have different survival strategies.Â If interested in this thesis have a look at aspbergers2.tripod.commervyn@tgeksupport.net.au

Check these dates again:Â Â New evidence confirms suspicions that early modern humans, which left Africa some 300,000 to 750,000 years before Neanderthals, probably interbred with the physically stronger hominid species. The contact likely happened in the Middle East, the authors said, sometime after early modern humans left Africa 80,000 to 50,000 years ago.

Just how many groups of erly modern humans left Africa and when?Â Do they mean erectus? Were we "early modern Humans" 300,000 years ago? Something's fishy there.

What's really funny about this is what it will do to the White Supremacists. Â It will blow their little minds. Â Their ancestors include Neandertals, but black Africans are pure Homo sapiens. Â Chortle, chortle.

This is actually phenomenally explosive news! Why has there not been more coverage of this in the news? Is it because it is not politically correct? Does this mean that black Africans and the rest of the world are different species? Please clarify.
